Description

4 pole connecting rod 40ka Surge special Circuit Breaker UL flame retardant


Surge Special Circuit Breaker (SCB) product feature:
40KA(8/20us) discharge current capability
UL94-V0 flame retardant

Novel appearance, 4 pole connecting rod design, 72mm

Golden Promise

Standard guide rail installation

The ability to withstand the impact of current is strong, no wrong action;
Power frequency current through more than 3±1A trip;
Running short circuit current breaking ability is strong;
Residual low pressure, protect equipment handy.effect is more better than fuse
High short-circuit current with maximum amplitude of 100kA can be cut off to protect SPD from TOV damage.
It can withstand the limp or lmax corresponding to SPD and keep on opening, and perfectly cooperate with SPD discharging current

The fuse, circuit breaker work with SPD can not do:
1, SPD deterioration, distribution line abnormal overvoltage, Can cause SPD to lead short circuit to the ground, fuse and circuit breaker can not break fast at this time, SPD fire frequently occurs.
2, when there is a lightning strike, because the fuse and circuit breaker design in the early stage as distribution components used, can not bear the instantaneous energy of lightning current, resulting in device explosion and tripping, SPD failure at this time.
3. When the lightning current passes through the circuit breaker, the Up value (voltage protection level value) is very high, and the SPD cannot play a protective role.
4, the fuse, circuit breaker short circuit analysis ability can not be used in thetransformer into the line, short circuit accident can not be cut off.

SCB series connection in front of SPD can do:
1.SCB can quickly cut off the access to prevent the lightning protection device from catching fire when the lightning protection device deteriorates and the distribution line has abnormal overvoltage, so that the lightning protection device conducts short circuit. Cut off current less than 3A;
2.When there is a lightning strike, the SCB connected in series in the front end of the lightning protection device can ensure that the 100KA lightning does not trip, not damage. To ensure the continuous and effective function of the lightning protection device;
3.The Up value (voltage protection level value) of SCB is very low when it passes through the lightning current, which is equivalent to the copper conductor of equal length;
4. Short-circuit breaking capacity exceeds that of MCCB up to 100KA;

SCB Application:
It is applicable to the places where SPD lightning protection equipment has been installed, such as: industrial and civil construction, electrical, communication, road traffic, petrochemical and other industries of power equipment
